Mixing Actives into Toner

Hello! Welcome to MySkinRecipes. It's great that you're exploring making your own skincare.

Regarding your plan to mix Alpha Arbutin (2%), Vitamin B3 (4%), and Glucosamine (4%) into Abhaibhubejhr toner, here are the answers to your questions:

• Can it be mixed? Yes, generally these ingredients can be mixed into a water-based toner like the one you have. Alpha Arbutin, Vitamin B3 (Niacinamide), and Acetyl Glucosamine (the cosmetic form of Glucosamine, often sold as GlucoBright) are all water-soluble and are effective within a pH range typically found in toners.

• Will the texture be sticky? Adding a total of 10% powder ingredients (2% Alpha Arbutin + 4% Vitamin B3 + 4% Glucosamine) to a liquid toner will likely increase its viscosity and may result in a slightly thicker or stickier texture compared to the original toner alone.

• Necessary to store in the refrigerator? While Vitamin B3 and Glucosamine can be stored at room temperature, Alpha Arbutin is recommended to be stored in the refrigerator for long-term stability. Since your mixture contains Alpha Arbutin, storing the final product in the refrigerator is advisable to help maintain the efficacy of the ingredients, especially Alpha Arbutin.

• Need to add a preservative? The Abhaibhubejhr toner already contains a preservative (Phenoxyethanol). This preservative helps prevent microbial growth in the original product. When you add other ingredients, you can potentially introduce contamination and dilute the preservative's effectiveness. While the existing preservative should provide some protection, the stability of the final mixture is not guaranteed without further testing. However, you do not necessarily need to add another preservative if the existing system is robust and you mix the ingredients hygienically.

Remember to mix the powders thoroughly into the toner until fully dissolved. Start with a small batch to see how you like the texture and feel on your skin.
